This replaces the obsolete 1.35V mercury batteries with either one 3V CR-1/3N or two 1.5V LR44 or SR44 batteries.
Note: This camera's meter was designed to run off two 1.35V batteries (2.7V in series). Using one 3V or two 1.5V batteries will cause the light meter to read higher than normal leading to underexposed photos. You will need to compensate by setting the ISO higher. My camera reads about 1 stop higher. So for 100 ISO film I set the ISO to 200. Your camera may be different so make sure to check this against another camera or a light meter app. The positive battery tab on the screw cover will need to be bent up higher as the original batteries are taller,
